## Homework Statement

A 1200 kg car traveling at 13 m/s is able to skid to a stop over a distance of 30 meters. What must be the coefficient of friction between the road and the tires for this to be possible?

m= 1200kg

Vo= 13 m/s

V= 0 m/s

x= 30 m

## Homework Equations

I think this is kinetic friction so:

fk=µkFn

## The Attempt at a Solution

I know I want to solve for µk but we haven't been over this in class and I am not really sure how to solve for it. I also don't know how I arrive at fk and Fn from the info I was given.
